Current Avenues of Research:

Predictive Validity of Rehabilitation Counselor CredentialsWe are examining whether counselors with a master's degree in rehabilitation counseling
end up having higher job-placement rates for clients than counselors with other types
of degrees.

Careless Responding in Online Survey ResearchWe are exploring seven different ways of encouraging study participants to carefully
answer survey items in order to prevent the collection of poor-quality data. The study
particularly focuses on participants recruited via crowdsourcing websites such as
Amazon Turk.

Structural Validation and Development of Norms for the ATTID ScaleThe study uses a large, geographically representative sample to confirm the dimensional
structure of the Attitudes Toward Intellectual Disability Scale (ATTID)
